Technical Abstract

Certain example embodiments of this invention relate to ruggedized switchable glazings, and/or methods of making the same. The PDLC stack of certain example embodiments includes an outer substrate, a low-E UV blocking coating deposited on an inner surface of the outer substrate, a first PVB or EVA laminate, a first PET layer, a first TCO layer, the PDLC layer, a second TCO layer, a second PET layer, a second PVB or EVA laminate, and an inner substrate. The substrates may be glass substrates. The low-E UV blocking coating may include at least two layers of or including silver and/or may include one or more IR layers. Thus, certain example embodiments may advantageously reduce one or more problems associated with residual haze, color change, flicker, structural changes in the polymer and/or the LC, degradations in state-switching response times, delamination, etc. The PDLC stack of certain example embodiments may be used in connection with any form of coated article, such as, for example, windows, windshields, IG units, etc.
